Overall we enjoyed the stay. The location is very nice. 5 minute walk to Sukhumvit 11, where you can enjoy bars, restaurants almost 24/7. 10 minutes away (walking) to Nana Pier, where you can take a boat to or from Center.
The apartment was super clean, well furnished, everything seemed very new. The bedroom had many windows and was facing sunrise so it was a pleasure waking up with the sun every day.
The swimming pool and library were out of service at the time of our stay, but the owner made a generous refund, so it was fair. When we were moving out it seemed that the pool was almost fixed, so, should be no problem now.
Def recommend the place :)
